Because: * CT is after the fact, plausibly too late. * As I mentioned before, CT is often impractical for typical domains != google.com. - They need to track the CT logs - They need to keep track of all legitimately issued certificates. - They need to detect unauthorised issuance quickly and have a mechanism in place to demand revocation. - Clients need to actually support CRLs, OCSP, ...

Not. It certainly isn't a secret, has been discussed on many lists over the years, but I don't know of a canonical place to find this advice. We could publicise this better, not sure whether an IETF BCP would be the right mechanism. Yes, you're unlikely to learn this from a discount registrar competing only on price and not on quality/security of service. -- Viktor.
